Definitions

  • Support roller bearings are roller or slide bearings that are used to guide components in various applications. Be in the field of aviation these support roller bearings for support z. B. the flaps are used.
  • the invention has for its object a seal for a support roller bearing to create the one unit between the outer ring and thrust washer creates and on the other hand fulfills the required sealing properties.
  • the sealing lip designed so that it lies in the recess in the outer ring during operation and When filling up the grease, release excess amounts to the outside can.
  • Another significant advantage is that the arrangement of the Sealing lip in a recess, the sealing lip through the annular approach is protected on the outer ring, so that no medium is directly on or directly below can inject the sealing lip.
  • the seal can be used for both slide and roller bearings. and cam rollers can be used.
  • Figure 1 is a roller-bearing support roller consisting of outer ring 1, inner ring 2, rollers 3, thrust washer 4, sliding washer 5 and seal 6 shown.
  • the inner ring 2 is provided with a relubrication channel 14. Solutions with one or two rows of rolling elements are not shown individually in the drawings, since the type of rolling bearing is not a feature influencing the invention is. Instead of the rolling elements, sliding layers can also be used.
  • the Seal 6 is designed as a plastic component.
  • the ring-shaped approach inside 6a of seal 6, engages in circumferential groove 4a of thrust washer 4 on. In the axial direction, the seal 6 is positively secured in the groove 4a.
  • the leg 6c of the seal 6, which runs obliquely outwards, ends with the Sealing lip 6d.
  • the slope of the leg 6c is chosen so that this sealing lip at internal pressure z. B. opens when refilling grease and the excess fat can thus escape to the outside.
  • the sealing lip 6d lies elastic in the recess 1a.
  • the annular approach to the outer ring 1b protects the sealing lip 6d from direct exposure to media.
  • the distance of the gap 7 between the sealing lip 6d and the annular Approach to the outer ring 1b is selected so that the seal 6 can easily snap into the recess 1a.
  • a plastic washer 5 is arranged between outer ring 1 and thrust washer 4, to reduce friction to reduce.
  • FIG. 3 a support roller with pin 11 is shown. Here is a thrust washer connected in one piece to the stud bolt or pin 11. The function the sealing element is the same as in FIG. 2.
  • FIG. 4 shows a support roller in which the two inner rings 12 are made in one piece are integrated with a thrust washer.
  • the seal functions as described in Figure 2.
